Hi all

I am conducting a meta analysis of pearson r correlations. I have converted these into fishers z to analyse in SPSS. Some studies presented more than one correlation , but measuring the same construct with the same method. I have averaged these correlations via fishers z but I now have a problem in that I need to calculate a standard error and the deviance which , I believe , requires one sample size per correlation.

I am wondering if it is acceptable to calculate an average of the sample size by combining the samples and dividing by the number of samples please?
